childManager property

@override SuperSliverMultiBoxAdaptorElement get childManager

The delegate that manages the children of this object.

Rather than having a concrete list of children, a RenderSliverMultiBoxAdaptor uses a RenderSliverBoxChildManager to create children during layout in order to fill the SliverConstraints.remainingPaintExtent.

Implementation

@override
SuperSliverMultiBoxAdaptorElement get childManager =>
    super.childManager as SuperSliverMultiBoxAdaptorElement;
